Ruby：捕获异常后继续循环

Question

基本上，我想做这样的事情（用Python或类似的命令式语言）：

for i in xrange(1, 5):
    try:
        do_something_that_might_raise_exceptions(i)
    except:
        continue    # continue the loop at i = i + 1

我如何在Ruby中执行此操作？我知道有redo和retry关键字，但它们似乎重新执行“try”块，而不是继续循环：

for i in 1..5
    begin
        do_something_that_might_raise_exceptions(i)
    rescue
        retry    # do_something_* again, with same i
    end
end

Answer 1

在Ruby中，continue拼写为next。

Answer 2

for i in 1..5
    begin
        do_something_that_might_raise_exceptions(i)
    rescue
        next    # do_something_* again, with the next i
    end
end

Answer 3

打印例外：

rescue
        puts $!, $@
        next    # do_something_* again, with the next i
end
